Polymorphic varieties. eleven Strings, that are sequences of characters written among double fees and are of style string. 12 the worth () and its variety unit. enter channels of variety in_channel and output channels of kind out_channel. integrated services for analyzing from and writing to them respectively. thirteen References of sort α ref. development them utilizing ref, gaining access to their contents utilizing ! and updating them utilizing the := operator. Bracketing expressions including start and finish rather than parentheses for clarity. acting an motion repeatedly in line with a boolean situation with the whereas boolean expression do expression performed build. appearing an motion a hard and fast variety of instances with a various parameter utilizing the for identify = begin to finish do expression performed build. Arrays of variety α array. growing an array with the integrated functionality Array. make, discovering its size with Array. size, getting access to a component with a. (subscript). Updating with a. (subscript) two hundred has variety bool simply because this can be the kind of the results of the comparability operator >. It evaluates to real. equally, 1 <> 1 has sort bool and evaluates to fake. The expression precise || fake is of style bool and evaluates to precise given that one of many operands is correct.
